[Clamav-devel] Streaming support in ClamD

Hi Guys,
I am new to Clamd and was trying to use it for virus scanning.
I used squid + icap + clamAv.
But i seen once all data is recieved clamAv INSTREAM is called and data is
passed to it.
Is it issue with icap server or Clamd doesn't support streaming support?
Any guidance will be helpful for me
and how can we make ClamAv streaming support.
Awaiting for reply.
